Supplementary data for the dissertation "Reader-friendly Edible Binarycodes and Sensors Based on Smart Hydrogel"

This is the supplementary data for the dissertation titled "Reader-friendly Edible Binarycodes and Sensors Based on Smart Hydrogel". This dissertation addresses the critical challenges of counterfeiting and product deterioration in the global food and medicine industries. It introduces four innovative prototypes to tackle these issues. The first prototype establishes a system for creating magnetic microparticles embedded with superparamagnetic colloids, forming binary code matrices for product authentication. The second prototype employs a Physical Unclonable Functions (PUF) algorithm to enhance the safety of On-Dose-Authentication (ODA) binary codes, making them readable even in basic laboratory conditions. The third prototype introduces a humidity indicator that reacts to high humidity by bending and rolling, providing a safe means to detect moisture exposure in food packages. The fourth prototype utilizes an alginate TTI bead encapsulating a natural colorant, betacyanin, to monitor and indicate temperature abuse in perishable products through irreversible thermochromic changes. These innovations hold promise for enhancing product quality control, tracking, and anti-counterfeiting measures in the food and medicine industries. The movies in this dataset are supplementary information regarding the magnetic microparticles embedded with superparamagnetic colloids and the humidity indicator separately.

本数据集为题为《基于智能水凝胶的可读食用二元编码与传感器》的学位论文配套补充数据。该学位论文针对全球食品与医药行业面临的防伪及产品变质两项关键挑战，提出四款创新性原型方案以解决上述问题。首款原型搭建了一套制备内嵌超顺磁性胶体的磁性微粒的系统，可形成用于产品防伪的二元编码矩阵。第二款原型采用物理不可克隆函数（Physical Unclonable Functions, PUF）算法，增强了单次给药认证（On-Dose-Authentication, ODA）二元编码的安全性，使其即便在基础实验室条件下也可被读取。第三款原型为湿度指示器，其可在高湿度环境下发生弯折与卷曲，为检测食品包装内的受潮情况提供了安全可靠的检测手段。第四款原型采用包裹天然着色剂甜菜红素（betacyanin）的海藻酸盐时间温度指示剂（Time-Temperature Indicator, TTI）微球，通过不可逆热致变色变化，对易腐产品的温度滥用情况进行监测与指示。上述创新方案有望强化食品与医药行业的产品质量管控、溯源及防伪体系。本数据集包含的视频文件，分别为内嵌超顺磁性胶体的磁性微粒与湿度指示器的配套补充资料。
